What are the causes of paper jams in the printer?

Paper is not good, change to paper with a high gram of 70g or more.

Then there is the printer that needs to be cleaned, and the paper feeding mechanism inside is too dusty.

Look at it again, the machine is not good.

HP's 7380 7580 all-in-one is hard to sell. Once, there was a ** member who worked hard to sell a lot, and the sales were the first. Originally, 'there is an additional reward for sales first', but HP deducted all the bonuses on the grounds that many warranty cards did not fill in the customer's e-mail.

Only 750 yuan will be paid as a minimum salary.

Someone sent an email to IT dealers in various places, saying that --- HP company gave a high kickback to the clerk who sold 7380 7580 850 5300 5400DN, but the boss suffered a loss of profits. Moreover, the unpacking of such machines is 23 out of 10 bad parts, and the energy spent on pre-sales and after-sales is five to six times that of other machines, which is not beneficial to customers and distribution companies. Look at its faults:

Some motherboards are faulty, some don't recognize ink cartridges, some keys don't work, some feeders don't feed paper, and there is a random ** line is broken, resulting in inability to send and receive faxes, and customers return them. Even if the machine works, it is as noisy as a tank, and the customer thinks there is something wrong.

And send this thing to Mr. Mark Hurd, CEO of HP Global Headquarters.

Now that the new product is about to hit the market, they will step up the sales of inventory. There is no fixed number of rewards for a product, there are completion awards, excess awards, ranking awards, regional awards, and some people can pay hundreds of yuan for a machine. Ladies and gentlemen, be cautious and calculate your profits.

People don't know that HP's laser machine is produced by Canon, and users will also have profits from Canon when they buy drums in the future, so HP must push inkjet, and ignore whether it is good for users.

Hello, for the printer jam you described; And "there will always be 4 very uniform black blocks on one side", and I personally think it is very likely that the heating main part is broken; Something may need to be replaced; It is recommended to go to the repair station and let the master help you take a look.

There are many reasons for paper jams. From the aspect of paper: one is the innate that the quality of paper is indeed poor. Second, the reason for the day after tomorrow is that the late paper is damp due to opening, and 2 is improper use. Also, even the machine often has problems! It's up to you to decide on a case-by-case basis.

As long as the paper of average quality is used correctly in the normal machine, there will be no paper jams!

Printer jam is generally a roller type chain paper, which is also a technical problem in the printer industry, there will be paper jams, but if the printing volume is not large, the frequency of the paper jam is mostly hardware needs to be adjusted, if the printing volume is large, but the paper jam is only 2-3 times a day is a normal phenomenon. To minimize paper jams, the paper should be placed artificially, parallel to the direction of the printer's paper feed, and the position of the paper should not be lower than the printer. Tear the paper to minimize uneven tearing.

If the paper is jammed frequently, it means that the speed of the chain feed cart motor and the roller is unbalanced. Lubrication is required.

Reasons for printer jams:1. Inferior paper or paper is damp. Inferior paper often has a lot of paper scraps attached to it, and the paper scraps fall into the machine during the printing process, which puts pressure on the paper roller and increases the possibility of paper jams.

If the paper is too light, it is also easy to jam. In addition, if the paper is wet, it will get wet, and the paper will be prone to jams.

2. There is a problem with the software configuration. Paper jams can also occur due to incorrect software settings. For example, if a paper drawer is filled with a different size of paper, but the A4 size paper is still set in the software settings, a paper jam will occur.

3. Aging of spare parts. If a printer is more than a year and a half old, its spare parts will begin to deteriorate, especially the wear of the paper roller, paper roller and separating jaw, which is also the main cause of paper jams.

The reasons for paper jams are: the printing paper is damp or sticking to the paper, there are shredded paper, and there is a problem with the toner cartridge.

Check whether the printer paper is damp or sticky to each other, because two or more sheets of paper will be released at the same time when printing, which will cause the printer to jam.

When the printer paper is not wet, turn on the printer to see if there are any pieces of shredded paper, and take out the shredded pieces to avoid paper jams in the printer.

When there is a problem with the toner cartridge, it will also cause the printer to jam, open the lid on the front of the printer, take out the toner cartridge first, and then pull out the jammed paper.

It should be noted that the paper must be picked up in the direction of the feed, and no knob must be turned in the opposite direction. If the paper is jammed frequently, check the paper feed channel to remove debris from the output path, and make the front edge of the paper just above the metal plate.

Check if the paper output roller is worn or the spring is loose, and the pressure is not enough, so the paper cannot be fed into the machine. When the paper roller is worn and cannot be replaced for a while, the method of winding the rubber band can be used for emergency treatment.

1. The printing paper is too thin or too much: it must be ensured that the quality of the printing paper is more than 60 grams, and the printing paper is too thin will cause the printer to become difficult when moving the paper, which is easy to cause the printer to jam the paper, and the printing paper can not be too thick at one time.

2. Wear of the paper roller: The paper roller is the most wearable part of laser printing. When the paper in the paper tray is normal and the paper cannot be taken, it is often the paper roller that is worn or the spring is loose; The pressure is not enough to transport the paper into the machine.

When the paper roller is worn and cannot be replaced for a while, the method of winding rubber bands can be used for emergency treatment.

3. There is a problem with the software configuration: if the software settings are wrong, there will also be a paper jam, for example, the paper box is stuffy and disturbed by other sizes of paper, but the software settings are still set to A4 size paper, so that the paper jam will occur.

4. Aging of spare parts: If a printer is used for more than one and a half years, the spare parts will begin to age, which is also the main reason for paper jams.

1: Paper roller: The phenomenon cannot be fed.

2: Stuck under the toner cartridge: It may be a laser, or there may be a problem with the fixing module, and the fixing film inside needs to be replaced.

3: Stuck where it appears: It is obvious that the fixer film is broken and needs to be replaced.

Inkjet printers: Generally, they are paper rollers, and there are many problems with the paper feeding component. Changing the paper roller may be normal for the paper feed assembly.

Laser printer: paper jams are more common, and the specific reasons for the occurrence of faults are mainly as follows: improper method of printing paper by device, opening the cover of the printer or adjusting the paper path rod during the printer printing, printing on the paper that does not meet the rules of the printer, using paper with a scale of less than 76 2x127mm, and the paper feeding parts are faulty or aging.

Maintenance process and cleaning method: During the printer operation, the printer will occasionally not move the paper, which will also jam the paper. If this is the case, the printer can press the paper feed button on the operation panel and the printer can move the paper.

If the paper cannot be moved, the following methods should be used to remove the problem: open the upper cover of the printer, take out the drum assembly, and check whether there is paper in the printer, especially whether there is any paper jam or paper debris in the paper feeding area and the paper output area to jam the sensor. Remove all media from the printer, rearrange it, and then put it back in the printer.
